WebIn terms of the basis of , it is straightfoward to verify that Here, are the components of the right Cauchy-Green tensor, and is the Kronecker delta symbol. The diagonal component fields are called axial , or tensile strains, while the off-diagonal component fields , with are called shear strains. The state of stress at a point in the body is then defined by all the stress vectors T associated with all planes (infinite in number) that pass through that point. However, according to Cauchy's fundamental theorem, also called Cauchy's stress theorem, merely by knowing the stress vectors on three mutually perpendicular planes, the stress vector on any other plane passing through tha…

WebApr 19, 2024 · The tensor is called the right Cauchy-Green deformation tensor. This tensor is often used when describing the constitutive properties of hyperelastic materials, for … WebSep 21, 2012 · 7,025. 298. Be careful about the terminology. Usually the Cauchy-Green tensor means a deformation tensor not a strain tensor. The Green Lagrange strain tensor is the "strain part" of the Cauchy-Green defiormation tensor. The "strain" is what is left when you take away the rigid body translation and rotation from the "deformation". cliff skeen

In 1839, George Green introduced a deformation tensor known as the right Cauchy–Green deformation tensor or Green's deformation tensor, defined as: C = F T F = U 2 or C I J = F k I F k J = ∂ x k ∂ X I ∂ x k ∂ X J . {\displaystyle \mathbf {C} =\mathbf {F} ^{T}\mathbf {F} =\mathbf {U} ^{2}\qquad … See more In continuum mechanics, the finite strain theory—also called large strain theory, or large deformation theory—deals with deformations in which strains and/or rotations are large enough to invalidate assumptions … See more The deformation gradient tensor $${\displaystyle \mathbf {F} (\mathbf {X} ,t)=F_{jK}\mathbf {e} _{j}\otimes \mathbf {I} _{K}}$$ is related to both the reference and current configuration, as seen by the unit vectors $${\displaystyle \mathbf {e} _{j}}$$ See more The concept of strain is used to evaluate how much a given displacement differs locally from a rigid body displacement. One of such strains for large deformations is the Lagrangian finite strain tensor, also called the Green-Lagrangian strain tensor or Green – St … See more The problem of compatibility in continuum mechanics involves the determination of allowable single-valued continuous fields on bodies.
